D. H. LAPplNTE PILOT LIGHT FOR OIL BURNERS Filed Novf 1, 1937 TiIIZJlf lllllllll INVENTOR DONALDHLAPOIN TE A; ATTORNEY Patented Dec. 19, 1939 UNITED STATES PILOT LIGHT FOR. OIL BURNERS Donald H. Lapointe, Meriden, Conn., assignor to The Miller Company, Meriden, Conn., a corporation of Connecticut Application November 1, 1937, Serial No. 172,123 4 Claims. (01. 158-94) The present invention relates to pilot lights for oil burners, and is more particularly directed toward a device effective to maintain a small pilot flame on the wick of an oil stove, so that it is 5 unnecessary to relight the wick each time the stove is to be started into operation.

According to the present invention the wick tube is provided with a notch in its upper edge through which it is possible to expose a small portion of'the periphery of the wick, when the wick is turned down or low, as to extinguish the flame on the remainder of the wick. This notch may be covered at will when the pilot light is not desired.

The accompanying drawing shows, for purposes of illustrating the present invention, two embodiments in which the invention may take form, it being understood that the drawing is illustrative of the invention rather than limiting the same.

In the drawing:

Figure 1 is an elevational view of a burner showing one form of construction;

Figure 2 is a vertical sectional view on the line 2-2 of Figure 1; and

Figure 3 is a perspective view illustrating a modification.

The wick tube It! may be of the conventional type having an inner tube or shell II and an outer tube or shell I2 adapted to receive the wick I3 and the wick carrier I4. The upper edge I5 of the outer wall I2 of the wick tube is notched, as indicated at IS. A fixed guide I! is suitably secured to the outside of the wick tube in a position below the notch I6.

able slider I8, the upper end I9 of which is shaped to fit the outerwall of the wick tube. The upper end of this slider is broader than the notch I6 and when the slider is in the upper position closes the notch. The lower end of the slider extends downwardly and outwardly to form a finger 26 to facilitate manipulating the slider.

In the arrangement shown in Figure 3, the

This guide carries a movouter wall 3|] of the wick tube is notched, as indicated at 3|. The guide 32 for the slider 33 is secured around the wick tube by a band, indi-' cated at 34. This arrangement is more particularly suitable for attachment to existing burners, it merely being necessary to cut the notch 3| in the material of the wick tube. This may be done by some suitable tool.

The wick I3 is preferably a wick of the type having a burning edge composed of asbestos 10 which is not consumed by the burning of the fuel, and, hence, the wick is not impaired by the pilot light whichburns opposite the notch. With this arrangement it is possible to adjust the oil stove flame in a manner analogous to a gas flame with 15 automatic pilot.

What is claimed is: I

1. In an oil stove, in combination, a wick, a wick tube having a notch in its side wall adapted. to exposea portion of wick surface when the 20 remainder of the wick surface is withdrawn into the wick tube, whereby a pilot light may be main tained, and a movable cover for the notch.

2. In an oil stove, in combination, a wick, a wick tube, having an notch in its side wall 2 adapted to expose a portion of wick surface when the remainder of the wick surface is withdrawn into the wick tube, whereby a pilot light may be maintained, a guide carried by the wick tube below the notchand a slidable cover-for the notch carried by the guide. I

3. An oil stove such as claimed in claim 2, wherein the lower end of the cover is extended outwardly to form a finger grip.

4.. In an oil stove, in combination, a wick tube, 35

a vertically movable slider carried by the outside wall of the wick tube and adapted to be moved from a position where its upper edge is at the same elevation as the top of the tube to a lower position, the wick tube having a notch which is covered and uncovered by said slider.
